A Comprehensive Analysis of Compression and Conductivity in Silicon-Carbon and Silicon Monoxide Anode Materials
Abstract Silicon-based anodes—including silicon-carbon (Si/C) composites and carbon-coated silicon monoxide (SiO)—offer theoretical specific capacities far exceeding graphite (372 mAh/g), but massive volume expansion (~300% for Si, ~160% for SiO during...
